英文原文:Explanation: No one on Earth sees the Moon rotate like this. That's because the Moon is tidally locked in synchronous rotation , showing only one side to denizens of our fair planet. Still, given modern digital technology , combined with many detailed images returned by the Lunar Reconnaissance Orbiter (LRO), a high resolution virtual Moon rotation movie can be composed. In fact, the featured time-lapse video starts with a view of the familiar lunar nearside and quickly finds the Mare Orientale , a large crater with a dark center that is difficult to see from the Earth, rotating into view just below the equator. In a complete lunar rotation condensed into 24 seconds, the video clearly shows that the Earth-facing nearside of the Moon contains an abundance of dark lunar maria , while the lunar farside is dominated by bright lunar highlands . Of course, you can just join other moon-watchers under hopefully clear skies tonight. Check out the sunlit portion of the lunar nearside on International Observe the Moon Night . 说明: 地球上没有人看过月球这样自转。这是因为月球被潮汐锁定在同步自转[4]中,只能向我们这颗美丽星球的居民展示月球的一面。 然而,结合现代数字技术[5]与月球勘测轨道飞行器[6](LRO)传回的许多详细图像,可以制作出高分辨率的虚拟月球自转视频[7]。 事实上,这段精选的缩时视频[8]从熟悉的月球正面[9]开始,迅速找到东方海[10],这是一个大而中心黑暗的陨石坑,从地球上难以看到,它在赤道下方旋转进入视野。 在24秒内压缩的完整月球自转中,视频清楚显示出面向地球的月球正面拥有丰富的黑暗月海[11],而月球背面则以明亮的月球高地[12]为主。 当然,今晚在希望晴朗的天空下,你也可以加入其他月球观察者[13]的行列。 在国际观月夜[14],观察月球正面的阳光照射部分。
